INCANDESCENT BURNER.

SPECIFICATION forming part of Letters Patent No. 561,449, dated J' une 2, 1896.

Application filed November 6, 1895.

`Serial No. 568,108. (No model.)

To @ZZ whom it may concern:

Be it known that I, Vieron II. SLINACK, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Incandescent Burners, of which the following is a specification.

My invention has reference to incandescent burners for hydrocarbon oils; and it consists of certain improvements, all of which are 1o fully set forth in the following specification and shown in the accompanying drawings, which forni a part thereof.

The object of my invention is to simplify Vthe .construction of an incandescent burner especially adapted for incandescent lighting, in which the hydrocarbonA oil is vaporized and consumed in the presence of a mantle of refractory material, which is thereby raised to incandescence. l

More specifically my object is to so construct the burner that the vapor is directly delivered to the burner'assoon as formed, thereby avoiding circuitous passages andreducing the `number of valves necessary.'

. My object, furthermore, is to avoid excessive heating of the hydrocarbon vapor,whic`h has heretofore been found exceedingly troublesome in burners as commonly found upon the market.

My invention will be better understood by reference to the accompanying drawings, in which-- Figure 1 is a sectional elevation of an incandescent hydrocarbon-burner embodying 35 my improvements. Fig. 2 is a vertical section on line a: of Fig. l.' Fig. is a sectional view on line y y; and'Fig. i is a sectional elevation of a modification of my burner,

showing it applied to a case where the burn- 4o ers are duplicated.

A is the generator, and consists of an inveri-ed cup or box shaped casting open at the bottom and formed with a rim A. Extending across the under side of the top portion 4 5 of the casting is ailue C, which connects with vthe pipe B, screwed into the castingA at one side and leading to a suitable source of gasolene or hydrocarbon oil. Pipe B is provided with a valve b for controlling the iiow of oil 5e to the generator. The top of the casting A is provided with a screw-threaded socket which opens into the horizontal flue C. Into this socket is screwed the burner proper, E. The 'flue O of the burner A, after extending across the casting, opens downward, as at O', 5 5 and into this is screwed the auxiliary-burner structure. As shown, this burner consists of 'an angular flue F f, terminating in a vapornozzle G, controlled by avalve g. Arranged above the nozzle G, and between it and the generator-casting A, is a tubular hood H, through which the vapor, together with the air drawn in at the bottonnpasses, and above which it is burned in the under part of the generator A. The hood II extends down near thev nozzle G, so as to protect the flame therefrom being blown out by excessive drafts of air.

The burnerE consists, essentially, of a vertical tubular part I, having a nozzle M at its lower portion which iits into the socket -D of the generator and a suitable burner .I at the upper part. The lower portion of the tubular part I is provided with a chamber K, having air-passages 7c and a valve-plate L for controlling the supply of air to the incoming vapor. The vapor passes through the nozzle M, and after being mixed with the necessary quantity of air iinds its way upward to the burner J, from which it is burned with additional supplies of air in contact with thehood P, of refractory incandescing material.

O is a chimney supported upon a base N, suitably carried upon the burner-tube I. It is immaterial what form of incandescing refractory hood may be employed or what the special construction of the burner proper may be, as these parts may be modified.

It will be observed that oil entering the generator A is brought to that portion which is highly heated by the flame from the .auxiliary burner, and the vapor so generated instantly passes upward through the nozzle M into the burner and has practically no time in which to remain in the generator. It will be further observed that there are no circuitous or long passages through which the vapor and oil` are required to pass. This avoids irregular heating of the hydrocarbon oil and insures a more uniform temperature being maintained. Furthermore, it will be observed that as the hydrocarbon oil is delivered to the IOO burner instantly upon its being vaporized no excessive or extended area of heating is necessary, and consequently the lower portion of the burner-tube I does not become sufliciently heated to cause ignition of the vapor within the chamber K.

In the construction shown in Fig. 4 we have substantially that illustrated in Fig. l, but with the employment of two burners E E, which are connected with the generator through a transverse tubular arm R, having a central nipple D for attachment with the socket D and provided at its extremities with valves m to control the amount of vapor entering each of the burners. Ordinarily the valves m would not be necessary, but in the case of two or more burners E being supplied from the same generator it is advisable to employ these additional valves to prevent excessive supply of vapor to one of the burners at a sacrifice of the supply to the other. The lower parts of the burner-tubes I are provided with nipples M and nozzles M, as above, and the valves m are adapted to work in connection with the said nozzles to control the iiow of hydrocarbon vapor.

I do not confine myself to the minor details of construction, as they may be modified without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is

l. In a hydrocarbon incandescent burner, the combination of a generator consisting of an inverted-box-shaped casting open at the bottom and having arranged transversely across its top and integral with the walls thereof a Hue or passage-way formed with an upward opening at or near the middle, a supply-pipe for delivering hydrocarbon oil into the said iiue or passage-way of the said generator at one end, an auxiliary burner ar ranged below the generator-casting arranged to project its iiame vertically upward into the box-shaped casting of the generator and provided with a vapor-flue opening into the passage-way of the generator at the opposite end, and a burner arranged above the generator and opening into the upper passage-way thereof and provided with means for supplying air to the vapor before being burned.

2. In a hydrocarbon incandescent burner, the combination of a generator consisting of an inverted-box-shaped casting open at the bottom and having arranged transversely across its top and integral with the walls thereof a flue or passage-way formed with an upward opening at or near the middle, a supply-pipe for delivering hydrocarbon oil into the said Hue or passage-way of the said generator at one end, an auxiliary burner arranged below the generator-casting arranged to project its iiame vertically upward into the box-shaped casting of the generator and provided with a vapor-Hue opening into the passage-way of the generator at the opposite end, a circular burner arranged above the generator andopening into the upper passage-way thereof and provided with adjustable means for supplying air to the vapor before being burned, and a refractory incandescing material arranged above the burner and adapted to be heated by the flame therefrom.
